At the front of the road construction vehicle is a door and retractable ramp used when the Gray & Houseman Explosives Truck needs to enter or exit the garage: the door rises and the ramp descends during these procedures. The garage has a turntable for trucks. At the bottom of the door are two lighting array troughs which contain spectrometers and ultrasound probes. On the roof next to the top of the door is a demolition gun, used in conjunction with the explosive truck to clear obstacles from its path. Behind the demolition gun is an armoured explosives magazine. On the other side of the explosives magazine is the reconnaissance helijet's maintenance hangar. Underneath the hangar is the road construction systems control room. Next to the control room is the bedrock distribution chamber. Further down the vehicle is a mineral store circulation pump, a tarmac storage tank, and a nuclear fusion reactor. The reactor provides power to vehicle turbines below and road construction machinery. Above is the crew accommodation deck with a canteen, recreation areas, and crew cabins. There is a lift which links the crew quarters to the office and control room. On the deck above is the control room and the Project Managers' office. On the far left side of this deck is the drivers' cabin. A communications array is on the roof of this top deck.

The main control room sat at the very top of the machine (see cutaway drawing) and had adjoining offices for the Project Manager(Bob Gray).
J.B Lester sits at his control desk, the Demolition Gun Operator can be seen at his controls (bottom right) and another operator can be seen in the background.

In the front section of the vehicle is a huge garage, where the Explosives Truck was stowed. After re-entering the garage, the truck was rotated on a turntable to face forward, ready to leave again when needed.
